Windows only: Ever since every sysadmin's favorite offline Windows patching program AutoPatcher had the plug pulled on it by Microsoft, those without constant Internet access or looking to keep multiple Windows boxes up to date have been looking for a valid replacement. Offline-Update, a free download for Windows 2000 and newer, may not have the same easy-to-grok interface, but it does give you the same basic functionality. Choose updates for the OS or Microsoft Office program to download and then create a burn-able ISO. Pop the Offline-Update CD into any computer and an auto-run program will ask you to create backups and install the updates. I haven't had time to do serious testing with the update program, but everything went smoothly in creating an update CD from Vista Home Premium. Offline-Update is a free download for Windows 2000 and newer systems only.
